That would be fine, just all the accessors need to mask out NX explicitely.
I didn't have plans to code that up myself though.

it was ok because

Yes, but if you cast to long the result will be 32bit again. Or do you
rely on it being always used in 64bit signed context with sign extension?
While that might work it would seem rather fragile to me, just asking

Hi Ingo,
More patches:
- rearrange paravirt.h to remove duplicate code, and to make it easy
to drop in 4th level pagetable functions.
- fix a warning I got from clear_bit in pgtable.h
- fix up some bogosity in pte_modify
- mask NX from pte_pfn
The last two may help with the problem that
